Bacterial inoculants cut farm greenhouse gas emissions in half

Farming feeds the world, but it also releases nitrous oxide—a greenhouse gas hundreds of times more potent than carbon dioxide. Now, a fresh look at decades of research suggests a surprisingly simple fix might be hiding in the soil. By adding specific bacteria to agricultural systems, farmers could dramatically cut these emissions. In liquid culture setups, like those used in some advanced farming, emissions dropped by about 68%. Even in traditional soil-based fields, the reduction was substantial at around 43%. The analysis pooled data from 34 studies, giving a broad view across different farm environments. It’s important to note this research shows a strong link, not proof that the bacteria directly cause the drop. The studies varied in design, and the certainty of the evidence isn’t quantified here. Still, for scientists and farmers looking for eco-friendly tools, these bacteria point toward a greener way to grow our food.
